Multi Y Axis
Examples for using multiple Y-axes:
Explicit¶
By default all lines will go on axis 0, the one on the left side. A different axis can be
specified using the :axis operation.
/api/v1/graph?
e=2012-01-01T00:00
&q=
name,sps,:eq,
42,1,:axis
Explicit Bounds¶
By default all axes will pick up axis settings with no qualifier:
/api/v1/graph?
e=2012-01-01T00:00
&l=0
&q=
name,sps,:eq,
42,1,:axis
Bounds and other axis settings can be set per axis, e.g., this graph moves the constant line for
42 to a separate axis and sets the lower bound to 0 via the &l.1=0 parameter. This would
work as well for &u.1=100e3. Append the index after the l. or u. :
/api/v1/graph?
e=2012-01-01T00:00
&l.1=0
&q=
name,sps,:eq,
42,1,:axis
Axis Per Line¶
There is a convenience operation to plot each line on a separate axis.
/api/v1/graph? e=2012-01-01T00:00 &axis_per_line=1 &q= name,sps,:eq, nf.cluster,nccp-p,:re, :and, (,nf.cluster,),:by
If there are too many lines and it would be over the max Y-axis limit, then a warning will be shown:
/api/v1/graph? e=2012-01-01T00:00 &axis_per_line=1 &q= name,sps,:eq, (,nf.cluster,),:by
Palettes¶
The color of the first line on an axis will get used as the color of the axis. The intention is to make it easy to understand which axis a line is associated with and in an image dynamic clues like hover cannot be used. Generally it is recommended to only have one line per axis when using multi-Y. Example:
/api/v1/graph?
e=2012-01-01T00:00
&l=01
&q=
name,sps,:eq,
(,nf.cluster,),:by,
minuteOfHour,:time,
1,:axis
Though we recommend not using more than one line per axis with multi-Y, a color palette can be specified for a specific axis. This can be used to select shades of a color for an axis so it is still easy to visually associate which axis a line belongs to:
/api/v1/graph?
e=2012-01-01T00:00
&l=01
&palette.0=reds
&palette.1=blues
&q=
name,sps,:eq,
(,nf.cluster,),:by,
:stack,
minuteOfHour,:time,
1,:axis
